Introduction:

In this case study I will be answering some questions on nuclear power and debating whether or not we should be using nuclear power. I will be exploring nuclear power as it comes up a lot on the news and also I find it a very interesting topic. Nuclear power stations currently produce about a quarter of Britain's electricity

Reference: (http://www.bbc.co.uk/climate/adaptation/nuclear_power.shtml). I will be looking at the science behind nuclear power, advantages and disadvantages and will come up with a conclusion whether or not we should use nuclear power.

What is Radiation?

Radiation is energy that travels in the form of waves or high speed particles.

There are many different types of radiation that have a range of energy forming an electromagnetic spectrum. However we are referring to the types of radiation used in nuclear power, nuclear weapons, and medicine. These types of radiation have enough energy to break chemical bonds in molecules or remove tightly bound electrons from atoms. These types of radiation are referred to as 'ionizing radiation.'

Atoms

Nuclear energy is from energy the nucleus (core) of an atom. Atoms are tiny particles that make up every object in the universe. There is enormous energy in the bonds that hold atoms together. Nuclear energy can be used to make electricity. But first the energy must be realeaed. It can be released from atoms in two ways: nuclear fusion and nuclear fission

Nuclear fission

During nuclear fission a small particle called a neutron hits the uranium atom and splits it, releasing a great amount of energy as heat and radiation. More neutrons are also released. These neutrons go on to bombard other uranium atoms, and process repeats itself over and over again. This is called a chain reaction. Nuclear power plants use nuclear fission to produce electricity

Reference: (http://hyperphysics.phy-astr.gsu.edu/hbase/nucene/nucbin)

The fuel most widely used by nuclear plants for nuclear fission is uranium. Uranium is non-renewable, though it is common metal found in rocks all over the world. Nuclear plants use a certain kind of uranium (U-235)

Nuclear power has not been around for very long and yet we now question its ability to provide us with what we need; Its performance is not what we are questioning but the sustainability and the environmental impact it has on the planet. More and more nuclear power plants are being built and more and more plants that being dismantled. The money needed for both assembling and disassembling power plants is beyond extreme, can the world really continue on acting in this way. Throughout this case study I will be looking at the benefits and drawbacks of nuclear power, the critical dates in history that led to what we now have and the dangers of nuclear power but the core issue that must be stressed, that must be recognized as a priority, is questioning if nuclear power is sustainable?
